Far Harad Volcano is a biome that can be found in patches deep within Far Harad. They are mountainous regions of barren dirt and stone, with dead, charred trees, lavafalls, and plenty of volcanic craters. The sky is darkened by the clouds of smoke constantly generated by the volcanoes, and any waters that can be found here are blackened with ash. Nothing lives in this biome, due to its inhospitable nature.
Unlike most biomes, the volcano biome spawns in dozens of small patches in several different areas of the map. At the heart of the Far Harad Grasslands is a chain of volcanoes known to the local Morwaith as the Gates of Fire, which hold great religious significance for local tribes. There are a number of volcanic islands off the coast of Harad, especially south of Perdorogwaith and as part of a certain island off the coast of the Horn of Harad. Several patches of volcanoes are scattered throughout Perdorogwaith, and smaller patches can randomly generate within the biome as well, similar to sub-biomes in other regions.
These arid regions see very little rain; instead, like in Mordor, the volcanoes have ash storms during periods of inclement weather.
Upon entering a Far Harad Volcano biome, the player earns the achievement "Fires of the South".
As the volcanoes in this region are active and none of the locals are insane enough to build among active volcanoes, there are no structures in this biome. Volcanic craters, however, can be found frequently, which are good sources of obsidian and obsidian gravel, as well as lava.
This biome is almost entirely deserted, but the occasional Grey Demon appears here from time to time.
Half-troll - Vicious, inhuman savages that look like a mix of Men and Trolls. They are larger than the player and have dark skin, animal-like tusks and horns, and are without weapons or armour, wearing only minimal, raggedy clothes.
This biome is almost completely composed of stone and dirt, and thus it's good for mining, as ores like Tin, Copper and Coal are often exposed on the surface. Obsidian Gravel can also be found here, especially in volcanic craters, which are also plentiful sources of obsidian, which can be useful for certain players.
In addition, as with every biome in Far Harad except Perdorogwaith, the Volcanoes generate gemstones at a slightly higher rate than most biomes, akin to the rates at which they can be found in most mountain foothills, together with all of the usual ores.
